JOSEPH W. GAMBLE, OF OMAHA, NEBRASKA.

FIVE-HORSE GANG-PLOW EVENER.

SPECIFICATION forming part of Letters Patent No. 749,373, dated January12, 1904.

Application filed July 9, 1902. serial to. 114,910. (No model.)

To cat/l w/wm it may concern:

Be it known that I, JOSEPH W. GAMBLE, residing at 1528 North Sixteenthstreet, Omaha,

in the county of Douglas and State of Nebraska, have invented certainuseful Improvements in Five-Horse Gang-Plow Eveners; and

ings, which form a part of this specification.

This invention relates to anew and novel improvement in five-horsegang-plow eveners. The object of my invention is to provide an evener ofsimple construction adapted to be used in connection with a five-horseevener on a gang-plow and'so arranged that each horse will draw anequitable and evenly-divided portion of the load.

The aim of my invention is to provide an evener for a gangplow in whichthe instrumentalities will be so arranged that one horse travels in thefurrow and the remaining four upon the land side or upon the unbrokensoil.

In the accompanying drawings I have shown in Figure 1 a top view of afive-horse gangplow evener with portions broken away embodying myinvention. Fig. 2 shows a side elevation of the tongue and fork as usedin my invention. Fig. 3 shows a top view of the evener. Fig. 4: shows adetached detail of the auxiliary tongue. Fig. 5 shows a front elevationof an equalizer embodying my invention, while Fig. 6 discloses an endview with portions removed.

2. This reversible fork is pivotally secured at its forward end by meansof a bolt 8, as is shown in Fig. 2. This fork 7 is provided with twoopenings crossing one another at right angles. In Fig. 2 one of theseopenings is shown at n, the same registering with a like opening in thehead 9.

Secured by means of the bolt 8 to the doubly-perforated stem of thereversible fork is a tongue A, which is provided with the socketed head9, into which stem of the reversible fork fits, while below this head 9is provided with a projection 10, through which the bolt 8 passes below,securing the evener B, a detail of the evener being shown in Fig. 3.This evener operates in the form of a rockingmember, being pivotallysupported by means of the bolt 8.

The extending portion 11 of the tongue is slotted, as is shown at 12,this slot being of two diameters and being provided with two transverseperforations or openings, within the first of which is held the bolt 13,the second accommodating the bolt 14., as is disclosed in Fig. 2.

The bolt 13, as disclosed in Fig. 1, holds the forward perforated end (0of the auxiliary tongue 15. The end 5, which is also perforated, is bentslightly upward, so that the same will work upon the clevis 5, where itis held by means of the bolt 16. This rear end Z) is forked, so as tostride this clevis 5 similar to the manner in which the reversible fork7 strides the clevis, as will be understood in referring to Fig. 2.

The bolt 14, working within the larger end of the slot 12, supports ahinge-bar 17 which hinge-bar at one end is secured by means of the bolt19, as shown in dotted line in Fig. 1, thishinge-bar extending laterallytoward the land side of the plow and is provided with a pin 20, whichpin extends upward and is secured to the long bar O as used in myinvention, the dotted lines r :1; disclosing the length of this hingebar 17.

Secured to the evener B, which is bent slightly L shape at one end, isabolt 21, which secures the counterpart draft-bars 22 and 23, which arealso secured above and below to the long bar 0 by means of the bolt 24.This long bar is pivotally secured to the bolt 20 of the hinge-bar 17,and its remaining end is provided with a bolt 25, as shown in dottedlines in Fig. 1, which bolt is adapted to receive the draft-bars 26 and27, which draft-bars at the remaining ends are secured,by means of abolt 28,Within one of the openings 2 of the evener B. The pin alsopivotally supports the three-horse evener D, and the upper draft-bar 26also Works above this three-horse evener.

Secured at one end to the three-horse evener D is the swingletree 29,while to the bolt 30 is secured the two-horse evener E, provided withswingletrees 31 and 32, the swingletree 32 being adapted to receive thedraft-animal walking within the furrow. To a bolt 33, secured t0 theremaining end of the long bar C, is the doubletree F, to which aresecured the swingletrees 35 and 34.

It Will be noticed that the swingletree 34 is longer than any of theremaining swingletrees, and this is done for the reason that the horseat this end is thereby given more room, so that the draft will come nearthe center of the five horses, permitting the use of a shorter long barC than were possible if the outside swingletree were the same length asthe remaining swingletree.

In Fig. 3, where a top view of the evener B is shown, the openingadapted to receive the bolt 21 is marked 21, while the opening adaptedto receive the bolt 8 is marked 8.

My evener is so arranged that the main tongue A remains stationary frommoving to the right or left by the use and the aid of the auxiliarytongue relative to the clevis 5. The hinge-bar 17, however, oscillatesat the end where it is secured to the long bar C, While the evener B iscontinually rockingor oscillating while the evener is used, permittingthe instrumentalities to adjust themselves so that the three-horse andtwo-horse evener Will be permitted a backward or forward movement inequalizing the load in using the evener.

The reversible fork 7 is provided with two openings at the socket end,so that this fork may be turned ninety degrees in securing the same to aclevis vertically secured to the plowbeam in connection with which thisevener is to be used.

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is

In an evener of the character described, the combination with a clevis,of a reversible fork, a main tongue secured to said fork, an evenerpivotally secured to said main tongue, an auxiliary tongue secured tosaid main tongue and to said clevis, a hinge-bar pivoted near one end tosaid main tongue and extending toward the land side of the plow, a boltsecured to the land-side end of said hinge-bar, a long bar securedapproximately centrally to said bolt to pivotally secure said long bar,a two-horse evener secured to the land end of said long bar, athree-horse evener secured to said long bar near the furrow end, adraft-bar extending from the furrow end of said long bar and beingadjustably secured to one end of aforesaid evener, and a draft-barextending from the land end of aforesaid evener and being secured nearthe land end of said long bar, as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

JOSEPH W. GAMBLE.
